Nicht-Druck Solarwarmwasserbereiter (DZ)

solar water heater Vacuum tubes assimilat the advanced 12 layers of apattering deposition of rivalent element tevhnology, highborosilicate glass, gradual change of SS-C/CU selective complex absorptive coating. Through the interlayer, vacuum has an unique effect of thermo, with its temperature up to 400 degree of idle sunning, performing a strong heating abilitty.
